HAROLD M. FRIESLEBEN, OF SAN FRANCISCO, CALIFORNIA.

FLUSH-TANK CONTROL.

Application filed April 6', 1915.

T 0 all-whom it may concern:

Be it known that I, HAROLD M. FRIESLE- BEN, a citizen of the UnitedStates, and a resident of the city and county of San Francisco, State ofCalifornia, have invented a new and useful Flush-Tank Control, of whichthe following is a specification.

The invention relates to means for controlling the discharge of waterfrom flush tanks, which are used in connection with toilets and otherdevices and comprises a loose ball adapted to close the discharge outletand means for unseating the ball.

An object of the invention is.to providea simple and cheap flush tankcontrol of the class described.

Another object of the invention is to provide a flush tank dischargecontrolling means of the class described which obviates the use ofpacking 0r stuffing boxes.

Another object of the invention is to provide a flush tank dischargecontrol of the class described, in which the connection between theoperating handle and the appa-" ratus within the tank is placed out ofcontact with the water in the tank.

The invention possesses other advantageous features, some of which, withthe foregoing, will be set forth at length in the following description,where I shall outline in full that form of the invention which I haveselected for illustration in the drawings accompanying and forming partof the present specification.

The novelty of the invention will be included in the claims succeedingsaid description. From this it will be apparent that I do not. limitmyself to the. showing made by said drawings and description, as I mayadopt many variations within the scope of my invention as set forth insaid claims.

Referring to said drawings: Figure 1 is a top or plan view of a flushtank embodying my invention, the cover or top of the tank-being removed.Fig. 2 is a vertical section taken on the line AA Fig. 1. Fig. 3 is avertical section taken on the line BB Fig. 2.

The invention consists broadly of a tank having a bottom sloping towarda discharge outlet, a loose ball adapted to seat on said outlet andmeans for dislodging the ball to open the outlet, said means beingconnected,

out of range of the water in the tank, to a handle or other operatingmeans arranged on the outside of the tank. The connection between thehandle and the apparatus within the tank is usually made above themaxi-' mum water level in the tank, so that no packing or stufling boxesare necessary.

The tank 2 is provided with a bottom 3 sloping toward the dischargeoutlet 4, in which is seated a metallic nipple 5 which forms a seat forthe loose buoyant ball 6. The ball is preferably a hollow rubber ball,which when dislodged from its seat ascends through the water in thetank. Formed in the tank is an integral passage or chamber 7 which opensinto the discharge passage 4: below the valve seat, and this passage 7preferably constitutes the overflow passage for the tank, and for thatpurpose is open at its upper end which extends above thenormal level ofthe water in the tank. The inflow of the water into the tank iscontrolled by the valve 8 whichQis operated by the float 9.

Secured to the wall of the tank above the maximum water level anddepending into the passage 7 is a guide 12, which is engaged by a rod13. The rod 13 is bent at its lower end, so that its end is disposed inthe.outlet passage and is provided on its upturned end with a foot 14adapted to engage the ball 6 from below. The upper end of the rod 13 ispivotally connected to a lever 15 which passes through the wall of thetank above the maximum water level and which is provided on its outerend with a handle 16. By arranging the rod 13 in the overflow passage,with which all flush tanks are provided, a very simple discharge controlmeans'is possible. It is not essential that the passage through whichthe rod extends be the -overflow passage, but for the purpose ofeconomy, it is advisable that the overflow passage be used for thispurpose.

In operation, the handle 16 is turned, causing the rod 13 to be raisedand the ball 6 dislodged from its seat. The ball then floats up throughthe water and when the water has discharged the ball settles to theinclined bottom and rolls to the discharge outlet, sealing it againstthe discharge of water until the ball is again unseated. As the waterdischarges from the tank, the float 9 descends and opens-the valve 8 andas the tank again fills with water, after the ball has seated, the float9 is raised and the supply of water is cut off.

guide and having its lower end curved I claim: 1. The combination with atank having a discharge outlet passage, a loose ball seated "on saidoutlet and an integral overflow pasball, a lever connected to said rodand eX- tending through the wall of the tank above the level of theoverflow inlet and a handle connected to the lever.

2. The combination with a tank having a discharge outlet passa e s acedfrom the side walls of the tank, a loose ball, seated on said outlet, ofan overflow passage formed integral with a side wall of the. tank andextending laterallyat its lower end into the discharge passage below theball, a guide secured to the wall of the tank above the overflow inletand depending into said overflow passage, a rod arranged in the overflowpassage and engaging said guide and having its lower end bent to liebelow said ball and means for raising said rod to un-' seat said ball.

In testimony whereof, I have hereunto set my hand at San Francisco,California, this 1st day of April 1915.
